Press and hold the SET key for about 2 seconds. Press the + or MIN/MAX key to set the low outdoor humidity alarm value. 2. 3. Press and hold the SET key for about 2 seconds. The wind speed digit will start flashing. Press the + or MIN/MAX key to set the high wind speed alarm value. Press the ALARM key to confirm the setting. Press the SET key to switch on or off the alarm. (The showing of the icon ((( ))) means that the alarm is switched on. ) 30 31 4. Press the ALARM key once to return to the normal display mode. WEATHER FORECAST AND WEATHER TENDENCY WEATHER FORECASTING ICONS: Weather forecasting icons is displayed in any of the following combinations at the right bottom part of LCD: TENDENCY TENDENCY TENDENCY In case the wind speed exceeds the condition for high wind speed alarm, the value will be flashing, along with the corresponding high alarm icon ("HI AL"). User may press any key to stop the sound. HYSTERESIS To compensate for fluctuation of the measured data, which may cause the weather alarm to sound constantly if the measured reading is close to your set level, a hysteresis function has been implemented for each weather alarm. For example, if the high temperature alarm is set to +77°F and the current value moves to +77°F, the alarm will be activated (if it has been enabled). Now when the temperature drops to +76. 8°F or below and thereafter again increases to beyond +77°F, the data will be blinking, but no alarm will be activated. It has to drop to below +75. 2°F (with a pre-set hysteresis of 1. 8°F) so that the alarm can be produced again. Hysteresis values for the various weather data types are given in the following table: Weather data Temperature Humidity Wind speed Hysteresis 1. 8°F 3% RH 3. 1 mph Sunny Cloudy with sunny intervals Rainy For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. (Every time a new average pressure value has been obtained (once per minute), this value is compared with an internal reference value. If the difference between these values is bigger than the selected weather tendency sensitivity, the weather-icon changes, either for worse or for better. In this case, the current pressure value becomes the new weather tendency reference. ) If the icons do not change, either the air pressure has not changed or the change has been too small for the Weather Center to register. So you may adjust the "sensitivity" of the pressure change checking in the setting mode ­see WEATHER TENDENCY SENSITIVITY VALUE SETTING above. Note: The temperature or humidity data will keep on flashing even after a key has been pressed to stop the alarm or buzzer has been switched off, to indicate that the current weather condition is out of the pre-set limit(s) 32 33 However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy.
